Quote from : 1Q84 Book

It was a cruel world though. More than half of all children died before they could reach maturity, thanks to chronic epidemics and malnutrition. People dropped like flies from polio and tuberculosis and smallpox and measles. There probably weren't many people who lived past forty. Women bore so many children, they became toothless old hags by the time they were in their thirties. People often had to resort to violence to survive. Tiny children were forced to do such heavy labor that their bones became deformed, and little girls were forced to become prostitutes on a daily basis. Little boys too, I suspect. Most people led minimal lives in worlds that had nothing to do with richness of perception or spirit. City streets were full of cripples and beggars and criminals. Only a small fraction of the population could gaze at the moon with deep feeling or enjoy a Shakespeare play or listen to the beautiful music of Dowland.
